VISUO-PERCEPTIVE AND VISUO-CONSTRUCTIONAL DEFICITS IN LEWY BODY DISEASE

Dr. Barun Kumar

Abstract :

 Introduction and Background: Dementia is a chronic neuro–degenerative disorder characterized by progressive 

cognitive loss. Alzheimers disease and the Lewy Body disease are the two most common causes ofage–related 
degenerative dementia. Visuo–cognitive skills are a combination of very different cognitive functions being performed 
by the visual system. These skills are impaired in both AD and DLB. The aim of this review is to evaluate various studies for these visuo–cognitive 
skills. Methodology: An exhaustive internet search of all relevant medical databases was carried out using a series of key–word applications, 
including The Cochrane Liary, MEDLINE, PSYCHINFO, EMBASE, CINAHL, AMED, SportDiscus, Science Citation Index, Index to Theses, ZETOC, 
PEDro, and OT Seeker, and OT search. We reviewed all the articles till March 2013 with key words of: visual skills, visual cognition, Dementia, 
Alzheimers disease, Dementia of Lewy Body disease. Results: Although most studies have used different tests for studying these abilities, in 
general, these tests evaluated the individuals ability of 1) Visual recognition 2) Visual Discrimination 3) Visual attention and 4) Visuo–perceptive 
integration. Performance on various tests has been evaluated for assessing these skills. Most studies assessing such skills show that these skills are 
impaired in DLB as compared to AD. Conclusion: Visuo–cognitive skills are impaired in DLB. These impairments have evident neuropathological 
correlations, but the direct neurobiological etiology is difficult to establish.
